PER HAKANSSON, OF ESLOF, SYVEDEN.

ANTISEPTIC COMPOUND.

SPECIFICATION forming part of Letters Patent No. 580,213, dated April 6, 1897.

Application filed N v r 13, 1893. Serial No. 490,871. (No specimens.) Patented in Sweden October 1, 1892, No. 4,377, in France April 1, 1893, No. 229,107, and in Belgium April 8, 1893, No.104=,213.

To all whom it may concern:

Be it known that I, PER HfiKAnssoN, a subject of the King of Sweden and Norway, residing in Eslof, in the Kingdom of Sweden, have invented certain new and useful Improvements in Antiseptic and Preserving Agents, (for which patents have been granted to me in Sweden, No. 4,377, dated October 1, 1892; in France, No. 229,107, dated April 1, 1893, and in Belgium, No. 104,213, dated April 8, 1893,) of which the following is a specification.

My invention relates to antiseptic and preserving agents used for destroying micro-organisms, for neutralizing poisonous gases in the air, for arresting putrefaction, for dressing wounds, &c., and asa remedy for cutaneous diseases, sores, and inflammation; and it consists of a liquid compound composed, essentially, of acetic ether, alcohol, and a comparatively small proportion of acetic acid. The compound may be mixed with water and have other ingredients added to it, according to the uses to whichit is to be applied, as will be hereinafter explained.

For most purposes, and particularly when the compound is to be used only for washing or for treatment of short duration, the compound may be in the following proportions: acetic ether, ten to forty per cent; alcohol, twenty to fifty per cent; acetic acid, two to three per cent.

lVhen the compound is intended to be used, by evaporating it, for purifying the air of rooms, to preserve objects, or to arrest putrefaction, the compound may be used in a more concentrated form, as follows: acetic ether, sixty parts; alcohol, twenty to thirty parts; acetic acid, ten to twenty parts. This concentrated form of the compound is not, however, essential to good results.

\Vhere the compound is to be used as a dressing for a considerable time, one part of the compound having the proportions first given above may be diluted with from one to two parts of water.

lVhere the object to be preserved is submerged in the compound, the proportions and strength of the compound -must be varied somewhat to suit the kind of objects to be preserved and the mode of preservation.

Where the compound is to be used for purifying the air in rooms by evaporation or is used on the hair or person, perfumes may be added to it, and where its continued use on the skin renders the latter dry or harsh a little glycerin or some fat or oil may be added to the compound. If in its use color is likely to be afiected by the acetic acid, the proportion of the latter may be reduced.

When acetic ether is added to alcohol or to a mixture of alcohol and acetic acid, the effect is to produce a most powerful antiseptic and preserving agent, and yet one which contains no ingredient injurious or poisonous to man and which is not of itself injurious or poisonous to man. This is important, as it renders the use of my compound safe even in careless hands, which is not the case with antiseptic agents which contain poisonous ingredients. Poisonous is here used in the ordinary medical or chemical sense as indicating substances which if taken or inhaled in small quantities destroy human life.

WVhile I have specified the preferred proportions of the ingredients I employ in the compound, the really essential point in the proportions of such ingredients is that the acetic ether present shall be in quantity sufficient to cause the compound to act antiseptioally. I

Having thus described my invention, I claim-- An antiseptic and preserving agent composed of a compound of acetic ether and alcohol in substantially the proportions specified, with a comparatively lesser percentage of acetic acid.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
